Humour, black humour even, is how some people deal with tragedy. Its been that way since time immemorial and is not likely to change for political correctness any time soon. If it does, that would be pretty sad. How many funerals have people gone to where laughter afterwards soothes the pain for some? It's just what it is. Laughter at a funeral isn't an endorsement for death any more so than a bad joke about an Cop getting incinerated is an endorsement for how things were handled. It just is. And I won't apologize by the way for that.
